Remove SPARC sqrt wrappers (bug 21973).
This patch removes the SPARC-specific wrappers for sqrt and sqrtf.
These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling. They also do not serve a useful optimization purpose. GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time). Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.
The removal of the wrappers also uncovers, and fixes, an old bug.
32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a
sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl
was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to
hand to check for the sqrtl symbol in those). This disappeared,
probably with:

Add sparc optimized sqrt{,f}.
Removing the wrappers brings back the generic ldbl-opt logic for
creating such compat symbols, and so restores the compat symbol that
should be there. This could of course also be fixed in the wrappers -
but as noted above, the wrappers are optimizing a case it's not useful
to optimize, so the bug of the missing compat symbol serves to
illustrate the risks involved with the extra complexity of
architecture-specific function versions where not needed.
Tested with build-many-glibcs.py.
